We present an expression for the center-of-mass (CM) energy of two colliding general geodesic massive and massless particles around a Kerr black hole. We show that the CM energy can be arbitrarily high only in the limit to the horizon and then derive a formula for the CM energy of two general geodesic particles colliding near the horizon. To have an arbitrarily high CM energy, the angular momentum of either of the two particles must be fine-tuned to the critical value. We show that, in the direct collision scenario, the collision with an arbitrarily high CM energy can occur near the horizon of maximally rotating black holes not only at the equator but also on a belt centered at the equator. This belt lies between latitudes ±acos(√ 3 − 1) ≃ ±42.94°.
